The Ordinary Lactic Acid 5% + HA 2% by The Ordinary

Overview

Lactic Acid is an alpha hydroxyl acid that exfoliates the skin. The Ordinary Lactic Acid 5% + HA 2% offers very mild exfoliation and is supported with a purified Tasmanian pepperberry known to reduce signs of inflammation and sensitivity that is often associated with exfoliation.



This formula contains a studied Tasmanian Pepperberry derivative to help reduce irritation associated with acid use. This derivative is of plant origin and varies in colour seasonally and this colour variation may be apparent in the formula from time to time.


When to not use The Ordinary Lactic Acid 5% + HA 2%: Lactic Acid should not be used on sensitive, peeling or compromised skin. Please refer to additional sun protection note and other warnings in provided Directions.

 

This pH of this formula is approximately 3.8. Lactic Acid has a pKa of 3.8 and pKa is the most important aspect to consider in formulating with acids. pKa implies acid availability.  When pKa is close to pH, there is an ideal balance between salt and acidity, maximizing effectiveness of the acid and reducing irritation.  Higher pH numbers in such a case would increase salt which counter-intuitively would make the formula even more irritating than if the formula was more acidic.

We suggest this product be used within 12 months after opening.

 

All of our products are filled/measured by weight/volume so the product is correctly filled to 30 ml. The packaging does not accurately reflect the size of the fill. However, this is intentional as some air must be allowed at the top for the product to actually close.

smooting - 24-09-2018 by

really smooths out rough skin

Love! - 24-09-2018 by

I alternate this with salycylic acid every second night to combat the hormonal acne on my jawline (pregnancy yay!). Skin is soooo smooth the next morning and skin is definitely clearer

Couldn’t continue - 21-09-2018 by

At first I was enjoying using this but after few weeks it started breaking me out badly and had stop using. I don’t think anyone who has sensitive skin could be beneficial by applying onto the skin

Works! - 21-09-2018 by

This is one of the only skincare products I have tried that I can say has 100% worked for me! The only other ones would be Rosehip Oil and Carmex lip balm.

This took about a week for me to notice results, I have fairly normal skin but I get tiny random bumps and rough patches that this product completely clears up!

It took away those tiny bumps on my forehead and chin, and when I ran out, I noticed in the 3 weeks I didn't use this product that a couple bumps came back. I was glad that this product actually worked long term and didn't cause ALL the bumps to come back. I didn't have any tingling sensations or sensitive skin after using this.

My skin feels super smooth when I use this, and I'm happy to see some women used this during their pregnancy so it's nice to know this can be used continuously! You have to try it, you can't go wrong with the price!

Absolutely love it! - 19-09-2018 by

I use the lactic acid twice a week as part of my routine and as a spot treatment for breakouts. I used it during my entire pregnancy and had minimal break outs which was amazing!

I love this stuff - 17-09-2018 by

This is my second purchase of the ordinary and I use it wavers day. It makes my skin feel tighter and brighter. I will be buying again

Night Time Use - 09-09-2018 by

I definitely think that this is helping my skin. My skin has been a little sensitive recently but this still works amazing. I use it every night and it's been improving my blemishes and removing my acne scars. My skin peels off but not too much though so I love it!

Even skin - 06-09-2018 by

I found that this definitely helped even out my skin tone and helped exfoliate the dry skin near my cheek and nose

Ok product - 27-08-2018 by

Didn't love the smell or feel of this on my skin. I didn't really notice any benefits from this either. There are better The Ordinary products out there I think

Couldn't tell the difference - 27-08-2018 by

The ordinary products are nice and such good prices but I just couldn't really notice a difference with this one

Great product - 22-08-2018 by

I love this product, its not too harsh on my skin and It reduced the little pimples I commonly get across my forehead! Definitely saw a noticeable difference in my overall skin appearance after using! I would apply it on my towel dried face after showering, before using my daily moisturiser.

great introduction to chemical exfoliation - 22-08-2018 by

My skin tends to get quite dry during winter so I've been careful in testing out this product in patches on my skin. The result has been quite positive so far. I've had no irritation, apart from dry skin on my upper lip (probably just a sensitive area to avoid next time). I've seen some positive improvements on overall smoothness of skin and even on old Acne scars.

Great for beginners - 20-08-2018 by

I started using it a week ago. I love the exfoliation it does on my skin and it is hard not to notice the smoother skin on the next day. I have sensitive skin so not every part of my skin can take it. I'll need to avoid applying it on my upper lip area but the rest are fine.

My skin just hates everything - 14-08-2018 by

I have quite oily skin and when I saw everyone saying how amazing it is for that I just HAD to buy it! I can definitely see a difference when using this, however I have this issue with my skin that I have to be careful using products for oily skin because it can go from oily to dry so easily even with moisturising.
So unfortunately I cant use this as often as everyone else seems to because if I use it more than 2-3 times a week my skin will go really dry (but only in the oily parts?) But even with using it so little I sure still do see the difference it make with breakouts.

wanted to love it.. - 14-08-2018 by

I didn't really notice a difference in my skin with this serum, apart from the fact it did seem to keep my skin, somewhat smooth.

Fantastic - 13-08-2018 by

The Ordinary has shown me that not all AHAs are alike, in terms of potential irritation, how they work, or how they affect the skin. Glycolic can produce rapid results, but can also be a bit irritating if over-used. The Ordinary's Lactic Acid, on the other hand, kind of nibbles away at glue holding dead skin cells together and blocking your pores. (Salicylic actually gets into the pores and helps deal with the gunk in there).

This is an excellent formulation, and I love the use of pepperberry to reduce any potential irritation (although I've never experienced any). Brilliant product.

Great if new to chemical exfoliation - 13-08-2018 by

I started using this as I am new to chemical exfoliation but trust the ordinary products and quality.
I love how it is gentle on your skin but does what it says!
I feel I have high tolerance to acids and retinol so keen to try the 10% solution next.

Easy to use but made no difference for me - 13-08-2018 by

A pleasant product to use with a nice scent, however I noticed no improvement in my skin after using this product consistently for months. Obviously for the price of The Ordinary products it's not a huge loss, but might not be for everyone.

Light exfoliation and hydration - 03-08-2018 by

A really nice, easy to use product. Goes on like water and isn't too strong so you can use it regularly.
I used it once after dermal rolling (the next day) - big mistake...I had a bad allergic reaction with red marks on my face for a week. But so long as I'm not using it after rolling, this is a really mild product and I like using it every few days.

Smooth but yet to see a difference - 02-08-2018 by

I have oily/combo skin and it has made my skin so soft and smooth. I have used it for about a week and doesn’t seem my skin has changed. It is very gentle so good for acne prone skin but good to start off with then move to the 10% if necessary

Wow! Made my skin smoother and clearer. - 01-08-2018 by

This product is addictive! I want to keep using it all the time as it has made my face feel smoother and clearer. I have combination 30-something year old skin and I thought it might sting or tingle but I had no reaction. I use at night time and I have noticed an immediate improvement to my skin. I think this is a great introduction to this type of exfoliation.

This stuff is life-changing! - 26-07-2018 by

I have really oily, sensitive skin that is easily prone to breakouts. I thought I'd give this a try, since it was recommended by a friend and it is AMAZING. I use it every night and I wake up with my skin feeling smoother and less irritated. My breakouts have improved a lot also, and I find that stubborn blackheads and whiteheads have also disappeared over time. Can't recommend this stuff enough!!

Great starting point. - 24-07-2018 by

I used this product for a few weeks when I first started using the ordinary products. I moved up to the 10% as I wanted a stronger AHA. I love lactic acid as it is not only an exfoliator but it leaves your skin hydrated. These products are such a great price and you will see results.

Love it - 24-07-2018 by

I've never used any sort of product like this, but felt like my skin was dull and pigmented so thought I'd give it a try. My main concern was that my skin may be irritated but I have to say I think it's a great place to start if you haven't used acids before. I love how my skin feels in the morning after I use it at night (around 3 times a week). My skin is softer, brighter and generally fresher. I'll work my way up to the stronger version of this, but for the 3 weeks that I've been using it I have to say it's made a huge difference and my skin tolerates it really well (no tingling or stinging or irritation whatsoever). I love it.

A good alternative to glycolic acid - 20-07-2018 by

A lovely, milder version of the 10% lactic acid. I found this didn't strip my pores or break me out when acid toning like glycolic acid did. It didn't quite exfoliate enough for me so I graduated to the 10%. Aside from the lesser strength, a great product!

so cheap for such a good product :) - 12-07-2018 by

lactic acid really does wonders for dull, dry skin :) it leaves your skin soft and smooth ! I 'm actually surprised at how cheap this is because it does what expensive serums and other skincare products do for a fraction of the price.

Weekly Wonder - 08-07-2018 by

I use this as a treatment every week to help combat darker pigmentation and to give my face a good exfoliation. This product does those things very well and for the price it cannot be beaten. I love that I can layer it with other PM skincare products or use it as a stand alone treatment and get great results every time.

WOW! - 04-07-2018 by

I had no idea i needed this product until i bought it, i didn't even know what it did, but now I can't live without it! This has completely changed the appearance of my skin getting rid of so many pimples and dark pigmentation, leaving me glowing and refreshed every single day. It is such a beautiful and gentle chemical exfoliant. I would definitely recommend this

I love it! - 02-07-2018 by

Great product very affordable! I can see the difference overnight, my skin is much smoother and brighter. Would highly recommend it!

love this stuff - 27-06-2018 by

this improved my skins texture so much. it can tingle a bit, but nothing too uncomfortable. I anytime my skin starts to look a bit lacklustre, and the next morning there is a nice improvement.

Amazing - but too weak for me! - 25-06-2018 by

I was so excited to try the new Ordinary range because I've heard so many amazing things about it. I purchased the Lactic Acid 5% + HA 2% because it was the lowest percentage, and I didn't want to overwhelm my skin.

Unfortunately, having already been using Dunk Elephant's T.L.C. Framboos Glycolic Night Serum, it looks as though my skin is already adjusted and I need a higher percentage! I didn't notice too much of a difference.

No complaints about this product though, just my own misjudgment. Definitely recommend to anyone who's never used acids before :)

Great for a beginner - 25-06-2018 by

Good product, would recommend. I noticed my skin feeling smoother immediately after use

Great chemical exfolaition for beginners - 20-06-2018 by

this was the first ever chemical exfoliation I used and I saw an improvement overnight!! It made my skin glowy and more bright after just a few uses and faded my hyper-pigmentation over time.

After finishing this bottle I purchased the 10% lactic acid and am also loving that one!!

Amazing for new acid users - 16-06-2018 by

I've never used acid before but it makes a huge difference to helping with dry skin! I use it every night and its improved the overall texture of my skin. I think if you have used acids before it may not be right for you and would be better off with a stronger one but for first time users this is great as it doesn't cause a reaction but still works well.

A gentle exfoliant that packs a punch! - 14-06-2018 by

This is one of my favourite go-to chemical exfoliants. It is light weight, and can be used each night to help break away any surface oil, dead skin and other things that can lead to blemishes and uneven skin tone.

Regular use of this product visibly leaves the skin feeling smooth and clear as well as bright and revitalised.

I like to use this product in conjunction with the Salicylic Acid 2% to help skin remain bright, youthful and blemish free!

Amazing! - 13-06-2018 by

I bought this after watching a youtube video and the girl had amazing skin. I didn't really know I needed this until I used it! I have combination skin and this lactic acid is such a gentle exfoliant and makes my skin so much brighter and clearer. Would highly recommend!

Very mild exfoliating serum - 12-06-2018 by

Having tried both the 5% and 10% versions of this serum, I much prefer the stronger one. If you have incredibly sensitive skin or rosacea, perhaps the milder one would be nicer, but I honestly don't think it had much effect. The 10% version is a really nice hydrating resurfacing serum. I use it once or twice a week at bedtime, applied to freshly cleansed skin, and wake up with soft, incredibly smooth, hydrated skin. It seems to help manage my cystic acne, and makes my skin lovely and silky.

Mild gentle AHA - 12-06-2018 by

This was my first introduction into AHAs so started off with the 5%. I was very wary of applying any acid onto my skin not knowing how my skin would react to it. This lactic acid is very gentle, even for newbies. I did not experience any tingling that was often reported and felt it was very mild. I did not see any difference from using this product, though it may be because I did not consistently use it. Next time, I'd probably try the 10%.

A great product - 12-06-2018 by

I have added this into my skincare routine. I have cystic acne and I am starting to see results

Great for rehydrating and resurfacing my dry skin! - 04-06-2018 by

This AHA has worked wonders with helping resurface and repair my skin especially in the winter months which makes it more prone to drying it out. The serum is amazingly hydrating for my skin and works well as part of my night time routine which has me using this on alternate nights to the ordinary retinol serum. With regular use my skin feels noticeably smoother and looks brighter. For the price of other comparable AHA products I do think this one is outstanding!
I did experience some slight stinging with the first few initial uses however this has subsided and resolved relatively quickly with no side effects.

Love The ordinary products but will try 10% solution next time - 23-05-2018 by

I really like how the ordinary is changing the market by bringing in good quality products for very affordable prices. I decided to try a chemical peel but have notice no difference with the 5% lactic acid solution using it every night.
I had been using one of their retinols and loving it as it was shrinking my pores and wanted to try swapping to lactic acid as I'm trying to get pregnant...
Will try the 10% lactic acid solution next time!!

INCREDIBLE - 21-05-2018 by

I use this every other day. Once it's soaked in my skin feels so much smoother. This is one of my faves and I get excited to use it! I have normal/combo skin and in the mornings my skin is so nice. Highly recommend.

Great for enlarged pores - 08-05-2018 by

If you can ignore the weird smell, this product is great. Has delivered results for my combo skin with oily T zone - my enlarged pores are definitely improved following use of this. I use a couple of times a week, at night, cycled with the Alpha Lipoic acid and retinoid.

First time acid user and love it! - 11-04-2018 by

This was the first acid I had tried and the verdict is in and I love it!

I use this every second day at night time as part of my skin car routine. It provides a gentle exfoliate which you can start to see results within minuets after using. I've been using the product for about 2 months now and no reaction - i cant wait to try the 10% in the future.

Great for those new to acids - 13-03-2018 by

A gentle exfoliant that will help anyone who is new to the world of facial acids.
Worked well with my combination skin and did not leave any reactions.

Gentle exfoliant - 27-02-2018 by

Nice, gentle exfoliant. You can see and feel the difference in like 3 minutes. Highly recommend.

Great acid to start with - 28-01-2018 by

Great product, have been using this over the past few months along with the Niacinamide 10% and the two products have cleared my acne and refined the texture of my skin.

I never experienced any stinging (granted, my skin isn't very sensitive) and it sank in quickly leaving no residue.

I won't repurchase as I'm stepping up to a stronger acid but definitely recommend this product to people who are starting to experiment with acids or anyone with sensitive skin as it is such a gentle formulation.

smooth skin after use - 11-01-2018 by

Good product, would recommend. I noticed my skin feeling smoother immediately after use.

Great for clearing acne - 19-12-2017 by

I love this. Along with the Glycolic Toner and Niacinamide from The Ordinary it has changed my skin. Using these in combination with using oils (marula, rosehip, almond and jojoba), gentle cleansers and nothing stripping, I have all but eliminated my adult acne. I think this is the real star though, helping clear blackheads and eliminate acne before it begins.
This smells a little funky, and is tacky feeling. I use at night only, and only twice a week.
Highly reccommend to those trying to clear their skin.

Affordable and effective. - 04-12-2017 by

I've been really enjoying using this product once a week. I feel like my skin is getting clearer. I've been using it at night and waking up in the morning with glowing skin. I like that it is not too harsh and that I am seeing results when I use this product.

Gentle exfoliation - 29-11-2017 by

I love The Ordinary's products and this does not disappoint. I have combination/sensitive skin and this works amazingly to control oil and shine without being too harsh. I use it only twice a week so this bottle will go a long way. Great price too.

Makes skin clearer and softer! - 13-11-2017 by

For the price, this stuff is amazing. I apply it with a cotton pad twice a week so I don't apply too much and dry out my skin. I use it alternating with a physical exfoliator and my skin is clearer and brighter. Definitely worth the price!

Super soft skin - 23-10-2017 by

I made the switch from physical exfoliators to this serum a couple of months ago and I'm never looking back. I have (very) dry skin and the flakiness of it can get out of control. Maybe it renews too quickly... I'm not sure, but I used to feel like I needed to exfoliate all the time and although it would give temporary relief, it just made my skin even drier. Now I use this stuff about twice a week and it's all I need. Especially the first morning after, my skin is so smooth! Despite my dry facial skin, I do get a greasy back (and bacne... Eewl!) and this really helps with that as well. So I feel like it would be good for all skin types. This doesn't irritate my skin and doesn't sting at all. It's just an allround winner. Highly recommend!

A must! - 24-08-2017 by

Put this on at night and you will wake up with clear, smooth and glowy skin. I have oily combo skin and this has controlled the oil slick. Loveeee

So gentle - 08-08-2017 by

I love this product, I find it super convenient! I struggle to use scrubs as I find them quite uncomfortable and harsh for my skin. This can be applied straight after cleansing on dry skin and that's it! I also have found it has helped control any congestion and breakouts.

Excellent Result - 02-08-2017 by

I am new to this product. I used to apply this everyday. This doesn't dry out my skin. My skin feels smooth now. Highly recommended.

Effective, affordable product - 16-06-2017 by

I have enjoyed this product so far. I have used pretty much every evening for the last two weeks and haven't had any irritation or issues.

Good for sensitive skin - 09-06-2017 by

I have been using this product for about 3 weeks on and off (I get lazy sometimes) and notice my face always feels smoother the next day if I use it the night before. My skin is crazy sensitive and I have not had a problem with this product at all. I'm really loving this!

Love love love - 18-05-2017 by

This product I put on at night and it makes my skin feel so soft by morning. Amazing product amazing price!
